NOTICE: Do not remove the speed oven door.

How to Remove the Oven Door

9WARNING

Make sure oven is cool and power to the oven has been turned off before removing the door. Failure to do so could result in electrical shock or burns.

The oven door is heavy and parts of it are fragile. Use both hands to remove the oven door. The door front is glass. Handle carefully to avoid breakage.

Grasp only the side of the oven door. Do not grasp the handle as it may swing in your hand and cause damage or injury.

Failure to grasp the oven door firmly and properly could result in personal injury or product damage.

To avoid injury from hinge bracket snapping closed, be sure both levers are securely in place before removing the door. Also, do not force door open or closed-the hinge could be damaged and injury could result.

Do not lay removed door on sharp or pointed objects as this could break the glass. Lay on a flat, smooth surface, positioned so that the door cannot fall over.

To help avoid injury or damage, be sure to read the above WARNING before attempting to remove the oven door.

1.Open the oven door to its fully open position.

2.Flip levers on hinges toward you.

Note: It may be necessary to use a tool, such as a screwdriver, to gently pry the upper part of the lever away from the housing. Take care to avoid scratching the housing.

3.Bring both door hinge levers to their fullest down position as shown in the illustration. The left and right door hinges differ slightly but operate in the same manner.

14

4.Close the oven door until it catches on the hinge stop levers, locking the hinges at the proper angle for door removal. The door will be open about 7 inches at the top. This takes the spring tension off the hinges so the door can be easily lifted out.

9CAUTION

PINCH HAZARD

Closing the door 7” takes the pressure off of the spring. If this isn’t done, the door can still be removed but the latch will now slam shut and will pinch or cut your hand.

5.The door is heavy. Use both hands to firmly grip it by the sides. Do not grip the door by the handle. Maintaining the door angle, lift the door straight up approximately 3/4” to unhook the hinges from the slots and then pull it out towards you until the hinges are clear of the oven housing.

6.Place the door in a convenient and stable location for cleaning.

Installing the Oven into the Cabinet

9CAUTION

It is recommended to wear gloves and long sleeves to protect hands and forearms from abrasion and potential scratches during the lifting process. It is also recommended to take off watches and jewelry and to wear work shoes during installation for foot protection.

9CAUTION

Three people or proper equipment are needed to safely lift the combination oven into the cabinet opening.

NOTICE: To avoid damage to the door, do not lift, pull or push the unit during installation by using any oven door handle as a gripping point.

Lifting Recommendations

There is a ridge across the top front of the oven cavity. Lift by grasping this ridge with one hand while placing the other hand on the back of the unit (for helpers lifting from the sides of the unit). If a third helper is lifting from the front, both hands should lift by holding this ridge area.

9CAUTION

DO NOT attempt to lift the unit by holding the oven’s upper heating element.

15

Proceed to lift the oven following the guidelines below with the door removed:

Lift points (1) on the front of the unit are for lifting from the sides of the unit. Lift point (3) on the front of the unit is for a third person to help lift the unit.

Lift point (2) on the back of the unit shows the location of the opposite hand for the helpers lifting from the sides of the unit. Adjust the location as needed to facilitate the lift.

Single Oven

Combination Oven

5.Install the supplied screws through the tap holes in the trim (2 screws for single ovens, 4 screws for combination ovens). It is recommended to drill pilot holes for the trim screws.

To ensure the door and oven function properly, the screws should be installed on the face of the side trim

6.Replace the oven door accordingly. See “Re-Install the Oven Door”.

How to Replace the Oven Door

1.Holding the door firmly in both hands, grip it on either side, not by the handle.

2.Tilt the door back slightly towards you until it opens about 7 inches at the top.

3.Slide the hinges into the slots as far as they will go and then lower the door straight down. The angle of the door may need to be adjusted slightly to allow the hinges to engage properly and the door to lower into place. The door should lower about 3/4” and stop. If not, the hinges have not engaged properly and the door could fall if it is released.
